LIFE-SAYING. DEVICE EUR SUBMHNE ETS Specialization of Apolicetiogi filed Gctoher 7,

To all wilma it my concern: I

Be it known that l, ERNEST Lenoir-snr, a l subject of the Emperor of Aiustrialllungary, residing at New York, in the county of New York and State of New York, have invented certain new and useful improvements in Life-Savin Devices for Submarine Boats, of Whichthe ollowing is a specification, referdrawing.V

vrlhis invention relates to a lite saving deivice tor submarine boats, and the primary objectoi my invention is to provide a subthat has sunk and cannot be raised in time to save the lives of the occupants.

Another object of this invention is to inrnish a submarine boat-with a Adevice that can he safely used for liberating each and every occupant of the submarine boat, the device being constructed to maintain a water tight connection when not in use.

A. further object of this invention is to provide a submarine boat with a life saving device that will occupy a comparatively small space within the boat and can be quickly operated to release an occupant of the boat without endangering the lives of operators remainingv in the boat.

These and such other objects as may hereinafter appear are attainedby the novel construction, combination andarrangernent of parts to be hereinafter described in detail and then claimed.

Reference will now be had to the drawing forming a part of this speciiication, wherein there is illustrated a preferred embodiment that the structural elements'thereoi can'be varied. or changed without departing from the spirit and scope oi the invention.

In the drawing :-l|`igure l isa side elevation ,of a submarine boat equipped with my imprdved life saving device, Fig. 2 is an' enlarged side elevation of the device, Fig. 3 is a, plan of the same partly broken away and'partly in section, Fig. i is a cross sectional view. ci the device in a closed posiandFig. 5 is a similar view oi the device in su open position.

intim@ drawings, the reference numeral l denotesthe deck or outer` shell of a submarine boat 2, and this decl: is provided with a rectangular opening 3 i'or'a cylindrical casing which is suitably mounted in said open- 1969. Serial No. 521,472.

ing and supported by the decir l. This ci lindrical casing,` is made in two vertical see tions et having the confronting edges therev of flanged, es at 5 and suitably secnrrfl'tov gather, the connections between the deci; and ,zasingg` being such es to prevent water entering the boat through the connections. The' casing is provided with two vertically alining rectangular' openings Z and 8, the open ing 7 being. located in top oi the casing above the decir, while the opening 8 is located in the bottom of the caslng beneath the deck.

Revolubly mounted in the casing is cylindrical drum 9, said drum having the ends thereof provided with journal pins l() and ll extending through the ends of the casing. The journal pin il is provided with a large gear or sprocket wheel l2 adapted to be slowly driven by a motor 13 or a suitable source or power located within the boat 2.'. rl`he cylindrical drum 9 snugly iits within the casing and is provided with a rectangular opening' l/l adapted to register with the openings I7 and 8. The drum 9 is mounted in the casing in such a manner that water cannot pass between said casing and said drum.

:As shown in Fig. d of the drawing, the opening` lli of the drum 9 registers with the bottom opening 8 or the casing` and communicates with the interior of the boat 2, and when the drum is'in such o position an occupant of the boat can easily enter the drum and assume ,a position somewhat similar to that indicated in Fig, ei. Betere entering the drum 9, the motor i3 is started to slowly rotate the drum and it is during1 the nieve-V ment of. the drum that an occupant. of the boat can enter the saine and adimt the hedor.'` during the movement of the drum so tobe in a vertical position ready to leave the drum as soon as the opening ltoi said-drain registers with the opening above the deck@ B startinc the motor before enteri'n the ...the water within the drum beingejected by gravity .before another occupant of the boat enters the drum. lt is immaterial what be' cornes of the last discharge of water after the last occupant has entered the drum.

ltisapparent from the novel construction of my life saving device that when the boat has sunk in a medium depth of Water the l @if the occupants thereof een be easily Saved thiough the medium of my devicefvf' ermite each occupant leaving the imanes/dient endangering the lives of the Having now described my invention what l claim as new, iszlife saving' device comprising the combination with a boat deck, 0f a transverselydiepe-.sed easing connected intermediate its top and bottoni and having the major portion thereof depending below the deck, Said casing' having an enlarged opening in its top end bottom, e cylindrical drum arranged Within seid casing and-having en opening adapted to regieter with ihe openings of the casing, journal pins xed et their inner ends to the inner face of the di'nn at the ende and extending through the ends of the e'sing whereby the drum is rotatably supported Within the casing, one ofseid journal pins of greater length than the other, a, relatively large sprocket Wheel mounted upon the elongated journal pin, and zz, tislnslnission belt :arranged below the deck and engaging with Said Sprocket for revolving the drum.

In testimoniY whereoiE l lailix my signature in the presence of two witnes'ses.
